ADJUSTABLE CHIMNEY-HOOD.

To all whom it may concern.-

Be it known that I, SAMUEL NEIBURGER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in AdjustableChimney-Hoods and I do declare the following to be a full, clear, andexact description of the invention, reference being had to the accompanying drawings, and to the figures of reierence marked thereon, whichform a part of this specification.

This invention relates to hoods or shields for chimney to s andespecially to hoods that revolve witi the changing air currents so thatthe wind will be prevented from blowing down the chimneys or preventingcontinuous drai't through the chimneys.

The objects of the invention are to provide reliable, strong and durablehoods for chimney tops including the supporting devices thereof, and toprovide apparatus of the above mentioned character that may be cheaplyconstructed and be convenient for shipment from factories to dealers.

l'Vith the above mentioned and other objects in view, the inventionconsists in certain novel parts, and in the combinations andarrangements of arts, comprised in an im proved adjustab e hood forchimneys, as hereinafter particularly described and defined in theclaims comprising parts of this specification.

Referring to the drawings, Figure 1 is a fragmentary elevation showingthe upper portion of a pipe comprising a part of the chimney top andhaving the improved hood mounted thereon and viewed at the rear thereofFi 2,'a vertical sectional view on the line A-A in Fig. 1 3 Fig. 3, afragmentary sectional view on the line B-B in Fig. 2; Fig. 4:, aninverted plan view of the hood proper and its vane; Fig. 5, a plan ofthe blank of which the hood proper and its vane is formed Fig. 6, aperspective view of the supporting devices of the hood proper; Fig. 7, atop plan of the supporting devices ar ranged on the top of the pipe in aslightly different manner from that shown in the other figures; Fig. 8,a horizontal sectional view on the plane of the line C C in Fig. 3 Fig.9, a vertical sectional view at the plane of the line DD in Fig. 8; andFig. 10, a fragmentary elevation of a building showing Specification ofLetters Patent.

its chimney provided with the improved hood.

Similar reference characters in the different figures of the drawingsindicate corresponding elements or features of construction.

In the drawings the numeral 1 indicates the upper portion of a pipe orchimney composed of metal and connected in Fig. 10 to the top of thebrick chimney 2 that projects from the roof oi the building 3. The hood4 forms the shield or deflector for preventing the wind from blowingdown the pipe and it is formed of sheet metal so as to be approximatelyscoop shaped 01' conical, and 1t has a vane formed integrally therewithand comprising an 11 )per rib portion 5 from which extend two sic eparts or blades 6 and 7 joined to separate portions of the hood at theplanes 6 and 7 respectively, at which the sheet metal is bent to permitof the two sides of the vane to stand opposite one to the othervertically and a )proximately parallel one to the other, the ood beingtilted over when in operative position and the vane extending upward andoutward from the upper portion of the hood in the usual manner. Thelines of junction of the sides or the vane extend from the peripheraledge of the hood to the apex 8 thereof, the rib 5 extending from theapex.

The stem of the hood, which serves as a socket for supporting andguiding the hood rotatively so as to be automatically adjust able to thewind currents, is preferably composed mainly of a bar of fiat iron orsteel and bent suitably, and it comprises an upper plate 9 havingbolt-holes 10 and 10 therein, the top of the plate being beveled so asto fit against the under side of the rib 5, which normally is inclined,the plate being arranged between the two sides 6 and 7 of the vane andhas an oblique-angled part 11 to which is connected a bearing member 12which, in its normal position, is horizontal and at right angles to thevertical plate 9, a guide member 13 being connected with the bearingmember 12 and having a guide opening 14 therein, the member 13 beingparallel to the member 12 and a short distance therefrom, a stem part 15extending from the member 13 at right angles thereto so as to benormally vertical and having a guide member 16 onthe lower end thereofthat is parallel to the member 13 and has a guide opening 17 therein. Aglass bearing plate 18 is placed against the under side of the member 12and is held in place by a clasp 19 having flanges 20 that engage themember 12, the clasp having an arm 19 extending up against the top ofthe inclined part 11 and having flanges 20 that engage the under side ofsaid part, the clasp havin an aperture 21 therein opposite the guideopening 14. The glass bearing plate is preferable for the purpose, butit will be understood that the bear ing plate may be composed of othermaterial than glass, and in the cheaper appliances may in some cases beentirely dispensed with. The vane is secured detachably to the upperpart 9 of the stem by bolts 22 and. 22, so that the hood prop-e issupported by means of the vane and in a very substantial manner.

For supporting and guiding the stem of the hood a cylindrical post 23 isprovided which is inserted through the guide openings 17 and 14 and hasa pointed upper end 24 on which the bearing plate 18 bears, thusdirectly supporting the member 12, and the post has a cotter 25 insertedin a suitable hole therein above the guide member 16 to prevent the stemfrom. being accidentally disconnected from the post, although if desiredthe cotter may be dispensed with in some cases when the hood and stemare sufficiently ieavy to prevent them from being blown off. The lowerportion 26 of the post is somewhat less in diameter than the mainportion thereof and has a shoulder 27 and also a threaded end. part 28on which is a threaded nut 29.

A frame is provided for supporting the post and comprises a fiat bar 36through the middle of which the smaller portion26 of the post isinserted in a suitable opening with j teriorate the mountings of thehood, espethe shoulder 27 engaging the top of the bar, the ends of thebar being turned over and.

forming downwardly extending arms 31 and i 31 adapted to engage theouter side of the hood will prevent the rain from drlving onto pipe 1. Athimble 32 is placed. on the part 26 of the post against the bar 30, andanother relatively shorter bar 33 is placed on the part 26 against thethimble and secured by the nut 29, the bar 33 having a suitable openingin the middle thereof to receive the threaded end 28, and the ends ofthe bar 33 are turned over and form upwardly extend.- ing arms 34 and34, the arms of the bar 30 having bolt holes 35 and the arms of the bar33 having holes 36 therein, and in attaching the frame to the pipe thebar 30 rests on the top of the pipe and the bar 33 is arranged on theinner side of the pipe with its arms opposite to the arms of the bar 30and the arms are secured to the pipe by bolts 37. The frame bars aresufliciently narrow to permit of there being ample draft passages at thesides thereof through the pipe.

In some cases when the pipe 1 is of relatively large diameter the framebar 33 may be turned so as to be at right angles to the vertical planeof the bar 30, as in Fig. 7, and connected to the pipe by bolts 38.

The blank for forming the hood and its vane of one sheet of metalcomprises an approximately oval part 39 of which to form the hood and anintegral part 40 of which to form the vane, the main portion of the part40 being slightly broader than the portion thereof at the points 41 and42 from which it extends from the part 39. The dotted lines 43 and 44extending from a point 45 approximately at the middle of the part 39 tothe points 41 and 42 indicate the lines on which the plates are bentwhen the part 39 is dished. The plate '39 has four bolt holes 46, 47,48, 49 arranged between the lines 43 and 44 and near the middle portion45, these holes receiving the bolts 22 and 22' that extend through theholes 10 .and 10 in the plate 9. The sides of the vane are formed bybending the part 40 on the broken line 50.

It should be understood that while the sides 6 and 7 of the vane areshown as being somewhat separated at their rearward edges which is forthe purpose of enabling the hoods to be conveniently nested for shipment, the sides of the vane may readily be pressed closer together whenattaching them to the plate 9. It will be clear also that the differentparts of theapparatus may be most conveniently packed for shipment andreadily connected together when mounting the hood.

In practical use the wind currents striking the rib 5 of the vane andthe sides thereof will operate as usual to adjust and readjust the hoodso as to deflect the air currents off from the top of the pipe 1, andthe gases emitted from the pipe will not materiallydecially when theglass bearing plate 18 is employed which will operate substantially as anon-corrosive anti-frictional bearing, and the the guide members 13 and16 so that the open work form of socket stemcannot in any case stickfast to the post .23 on accountof corrosion or soot.

Having thus described the invention, what is claimed. as new, is
